laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/34966?usp=email ) Change subject: logging_gsmtap: Temporarily disable logging when sending the logs ...................................................................... logging_gsmtap: Temporarily disable logging when sending the logs This avoids an infinite recursion when sending a gsmtap log message causes a log message. Temporarily set target->loglevel higher than LOGL_FATAL, which effectively disables logging for that target. Other targets like stderr will still log this message so there is still an indication that something went wrong.
